The core of his work is an overview of his most beloved places, from the famous cityscapes of metropolis such as New York, London and Paris, where he spent some years of his life, to the visions of the Italian Plane Pianura Padana, where he lived for more than 20 years, but also the Sicilian coast nearby Ragusa and the Venetian lagoon, are landscapes often represented by Tonelli as they mean a lot to him since they are buen retiro places. The leitmotiv of all of these subjects, so different from one another, is the search for a strong image of stability, expressed by simple, synthetic and balanced forms.
